Handpiece Lubrication
(See page 6 for handpiece photos.)
Numbers 8, 8D*, 18, 18D*, 20, 25, 25C, 28, 30
®
, 35, 44T, and 52:
These handpieces have been permanently lubricated with greased-shielded ball bearings and
should absolutely not be lubricated.
Number 10: Lubrication should not be required for the first 2–3 months of continuous use.
Then, approximately every two weeks, remove the sheath connector (it has a standard right hand
thread) to expose the slotted shaft connector and back of handpiece spindle. Clean off any dirt or
old lubricant. Apply only 1 or 2 drops of Foredom oil to the spindle where it attaches to the slot-
ted shaft. Now replace sheath connector.
Number 10D* Handpiece with Duplex Spring Connection: Approximately every 20 hours of
operation apply 1 or 2 drops of Foredom oil into the hole in the duplex spring collar next to the
sheath connector. This will provide sufficient lubrication for both the duplex spring connection
and the handpiece spindle.
Numbers 15 and 15D*: Before disassembling, clean off any dirt to prevent foreign matter from
falling inside the handpiece. Remove the threaded nosepiece assembly carefully with wrench
supplied by turning counterclockwise (right-hand thread). Put two drops of Foredom oil into the
bottom of the threaded hole of the housing and one drop into the nosepiece assembly. Replace
the nosepiece assembly, hold the handpiece upright and run it slowly to distribute the oil.
Lubricate every 100 hours of use.
*Note: All handpieces marked with asterisk have duplex spring connections (flexible springs in
middle). These connections must be lubricated once every 20 hours of operation. Apply about
two drops of oil into the hole on the rear of the connection collar. This should be done with
Foredom ® Hypodermic type oiler (Part No. 10005).
